The guide emphasises that consumers with disability may be vulnerable, such as those with intellectual disability.

And it adds: “Where businesses seek to take advantage of a consumer’s disability or vulnerability, the ACL regulators will not hesitate to take strong enforcement action.”

Along with the ACCC, the co-authors of the guide include the consumer protection authorities of all states and territories, as well as the Australian Securities and Investments Commission (ASIC).

The guide gives an overview of the laws and regulations that protect consumers, and create a fair and open playing field in the marketplace.

Additionally, it runs through the obligations of businesses, and how to treat customers fairly, along with case studies relevant to the disability sector.

In pre-NDIS days, providers would often supply their goods and services as an approved supplier to a welfare agency, usually a government department, or through a tender process. This demand-driven provisioning model placed the onus of ensuring a fair and open marketplace on the agency.
